Thanks, that worked perfectly I want the biblio number because we're using it as part of our matching rules during import. The biblio numbers are being added into the appropriate records pre-upload, because I can't write a matching rule that includes subtitle and edition. This will become even more useful when we import data from a branch which duplicates about 80% of what's already in the main collection. Thanks again!

Elaine, try this

select b.biblionumber, author, title, ExtractValue(marcxml, '//datafield[@tag="245"]/subfield[@code="b"]') as subtitle, ExtractValue(marcxml, '//datafield[@tag="250"]/subfield[@code="a"]') as edition, copyrightdate, place, publishercode, isbn from items as a left join biblioitems as b on (a.biblioitemnumber = b.biblioitemnumber) left join biblio as c on (b.biblionumber = c.biblionumber) where itype = 'BK' and holdingbranch = 'VWML' order by author asc;

Now, Why need biblionumber? That's one of Koha's internal numbers.

Regards, Bernardo

I'm trying to catch duplicate items in data before I upload it (ISBN won't help in this case). In order to do that I've written a report to list the books currently in Koha, and will compare them with my external files. However, if I can't include the subtitle (MARC 245 b) I will get too many false positives (we have lots of things with the same title, but different subtitles) It would also help if I could also have the 250 a (edition)

This is what I have: SELECT

biblio.biblionumber,biblio.author,biblio.title,biblio.copyrightdate,biblioitems.place,biblioitems.publishercode,biblioitems.isbn FROM items LEFT JOIN biblioitems on (items.biblioitemnumber=biblioitems.biblioitemnumber) LEFT JOIN biblio on (biblioitems.biblionumber=biblio.biblionumber) WHERE items.itype='BK' AND items.holdingbranch='VWML' ORDER BY biblio.author asc

This works fine, but doesn't include the 245 b or the 250 a Can anyone help? -- Elaine Bradtke Data Wrangler VWML English Folk Dance and Song Society | http://www.efdss.org Cecil Sharp House, 2 Regent's Park Road, London NW1 7AY Tel +44 (0) 20 7485 2206 (This number is for the English Folk Dance and Song Society in London, England.
